    Lenovo Ideapad 510s-14isk won't boot

    Hello, i'm looking for help to my laptop problem.

    Symptoms are strange.

    When the first power button is pressed, the fan starts spinning and turns off after 3 seconds.

    second try, the fan starts spinning again but stop after 5 seconds.

    final try, the fan starts spinning and don't stop, but screen is not shown.


    i checked voltage, and VCCCORE is a little strange but i didn't have any knowledge about VCCCORE, is it wrong? or something other problem?

    Remove the RAM and try again. Do you hear any POST beep code or see any different results now that the RAM is removed ?
